摘　　要：文章基于2006—2019年我国省际面板数据实证检验了数字化对交通运输碳排放强度的影响效应及其机制。研究显示,数字化具有减排红利,能够显著降低交通运输碳排放强度,且该种影响存在区域差异,在西部和高碳排放强度地区更为明显。机制检验表明,数字化能够通过促进绿色技术创新改善交通运输行业碳排放强度。拓展分析显示,数字化减排红利的长期效应依然显著,且随着数字化发展水平的提高,减排红利呈现边际效用递增的非线性特征。Based on the inter provincial panel data of China from 2006 to 2019,this paper empirically tests the impact of digitalization on transportation carbon emission intensity and its mechanism.The research shows that digitalization has emission reduction bonus,which can significantly reduce transportation carbon emission intensity,and there are regional differences in this kind of impact,especially in the western and high carbon emission intensity regions.Mechanism test shows that digitalization can improve transportation carbon emission intensity by promoting green technology innovation.Expansion analysis shows that the long-term effect of digitalization emission reduction bonus is still significant,and with the improvement of digitalization development level,the emission reduction bonus presents a nonlinear feature of increasing marginal utility.
